Need help with SfB Network Assessment Tool

Hello,

I've searched online and I'm unable to find a suitable answer. When I try and run the MSFT free Network Assessment Tool it fails. I've tried on a fully patched Windows 10 (Home) and a fully patched Windows 7 Enterprise system. (Both x64). Does anyone have any ideas or can point me in the right direction?

Audio call started. Waiting for call to end...Call should end shortly after configured duration of 17 s.

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Rtc.Internal.Media.dll'or one of its dependencies. The specified module could not be found.at NetworkAssessmentLib.AudioLoopbackSingleChannelPlayer..ctor(ProbeConfig probeConfig)at NetworkAssessmentTool.LoopbackCallExecuter.ExecuteCall_Blocking()at NetworkAssessmentTool.Program.ExecuteLoopbackCall(ToolConfig config)at NetworkAssessmentTool.Program.Main(String[] args)

Thanks Thomas. I previously found that article but all the patches say they're for Server Windows 8.1 and/or Server 2012. I'm seeing this on Windows 7 and Windows 10 that say they're fully updated. Is it recommended to try the patches in the order listed on Windows 7 and 10?

Tom, I was unable to find the SfB Basic .msi client. (Didn't spend too much time looking...) I did however download the .exe for my Windows 10 system. (Did not do it for Windows 7 because it is my work computer running SfB Enterprise.)

It actually fixed the problem on Windows 10! It works now which is good news. I'm assuming it would work for Windows 7 but I'd probably break something if I installed it over SfB Enterprise.

What was interesting is I found my laptop vendor, Toshiba, had installed MS Office 32-bit on my 64-bit machine so I had to use the 32-bit SfB basic client.

Hi Thomas

I am also getting the same error as mentioned by Richard Carrara. Today I Installed the new version 6.0.8969.164 which was published on 12/14/2016 and also the dependency Visual C++ run-time components for Visual Studio 2015 from https://www.microsoft.com/en-us/download/details.aspx?id=48145 but still getting the same error message.

I will appriciated any assistance to resolve the problem to run the tool.

@Dmitry Bulavin - The Usage.docx is being updated to include the specific requirement that the Desktop Experience feature is enabled when running on Windows Server editions. Please install and let me know if you are still having issues.

This Desktop Experience is a requirement for making calls with Skype for Business clients and since this tool uses the same core technology it has the same requirements.
